name crystallina can only stand for the British E. African form of the 

 ? of cJiilo, Godm. 



It is also perhaps worthy of note that chilo should probably 

 stand next acara in the fourth subgroup of Group I of Prof i ssor 

 Aurivillius' catalogue, having, as it does, a large black, white-spotted 

 base to the hind-wing under-side. This occurrence in Acrceince of a 

 transparent and presumably inconspicuous ? with a brightly coloured

DESCRIPTION OF A NEW SPECIES OF 3IIMACRMA FROM WEST 



AFRICA. 



BY H. ELTRINGHAM, M.A., P.E.S. 



MlMACR^A NEAVEI, 71. Sp. 



Expanse, 2'375 in. Upper-side; ground-colour dark umbcr-brown. Fore-wings 

 with an oblique subapical band of four oclireons-yellow spots, the first next the 

 eosta, very minute, the second and third subquadrate and about •125 in. in length ; 

 the fourth minute. A curved discal band of oehreous-yellow '25 in. wide extending 

 from the second median nervule in the fore-wing to the inner margin of hind-wing. 



Under-side : fore wing marked as on upper-side, but generally paler and the 

 subapical band paler than the discal ; there is also an ochreous suffusion over the 

 lower half of the discoidal cell. Two dark spots in the cell and one on lower 

 discocellular nervule. Internervular spaces of hind-margins in both wings bearing 

 pale elongated V-shaped markings. Hind-wing with pale ochreous discal band 

 corresponding with that on upper-side ; basal area pale ochreous dusted with dark 

 brown and bearing 14 black spots of irregular shape and size, as in many species of 

 Acrsea. Antennae dark brown with reddish club. Two white streaks and two 

 white dots between the eyes. Thorax and abdomen dark brown above and bright 

 oehreous-yellow beneath. 



Hahitat : Cameroona, W. Africa. 



The superficial resemblance of both the upper and under sides 

 of this Lycaenid to Acrcea oherthuri, Butler, is extremely striking, 

 these two species having been received by me under the same name. 

 I hope shortly to figure this remarkable form, together with its 

 Acrseine model. 



I hare much pleasure in dedicating the species to my friend 

 Mr. S. A. Neave, M.A., B.Sc, of Magdalen College, Oxford.
